Description of problem:

The issues are almost the same.

fv_core test log: 
Test Parameters: DEBUG=off RUNMODE=normal OUTPUTFILE=/var/log/v7/runs/1/fv_core/output.log DEVICE= TESTSERVER=10.66.65.181 
/proc/cpuinfo has vmx flag

Starting libvirtd daemon: 
libvirtd is running
Verified that guest v7x86_64 is not running
Verified: /var/lib/libvirt/images/v7data.img
Verified: /var/lib/libvirt/images/v7x86_64.img
Verified: /etc/libvirt/qemu/v7x86_64.xml

But run command: virsh start v7x86_64. 
Then the fv_tests PASS.

Steps to Reproduce:
1. provision x86_64 system with RHEL6.1-20110210.1 and install packages libvirt libvirt-python python-virtinst kvm-tools
2. install v7-1.3-10 and dependenies
3. run: v7 run -t fv_*
  
Actual results:

Exception occured in fvtest.py mountDataImage() and abort: 
290             Command("kpartx -av " + self.loopBackDevice).echo()

But run "kpartx -av /dev/loop0" on prompt successful:
# kpartx -av /dev/loop0
add map loop0p1 (253:3): 0 192717 linear /dev/loop0 63
Comment 3 chen yuwen 2011-03-03 07:25:14 UTC 
The error in RHEL6.1-20110224.2 is the same.
But the error don't occur in RHEL5.6.
Comment 5 chen yuwen 2011-03-04 02:28:16 UTC 
In test of #Description,  the loopBackDevice /dev/loop0 was already in use. So the loopBackDevice was /dev/loop1. 
#comment 2 was another test on another machine. The loopBackDevice was /dev/loop0. But the issue was the same.
